Description

Superfine powder huoxiang zhengqi powder normal temperature preparation method
Technical field
The present invention relates to the veterinary drug preparation field, especially relate to superfine powder huoxiang zhengqi powder normal temperature preparation method; The invention still further relates to the special-purpose two-way airflow screening machine for this method.
Background technology
Be applied to the huoxiang zhengqi powder that domestic animal prevents and cures diseases summer at present and mainly contain the powder that ten kinds of traditional Chinese medicines such as Herba Pogostemonis, Folium Perillae, the Radix Angelicae Dahuricae are formed, have separate in the harmony in the exterior, the effect of regulating QI to expel dampness, can suppress the intestinal smooth muscle activity, remove intestinal and smoothly reach spasm, staphylococcus aureus, the first and second type Salmonella paratyphi, dysentery bacterium are had the obvious suppression effect.Used powder exists that dosage is big, dosage form is thick, appearance poor, and effective ingredient can not fully discharge, and bioavailability is low to be waited not enoughly, has had a strong impact on Chinese medicine quality and therapeutic effect.
The broken technology of Chinese medicine ultra-fine powder is renewal and the development to traditional crushing technology; it had both kept the advantage of Chinese medicine technology of preparing; injected new vitality for the modern production of Chinese medicine again; have a extensive future, but remain in actual production in some problems and a difficult problem: (1) production efficiency is low, the power consumption height is the principal element of restriction Chinese medicine ultra-fine powder large-scale production for animals.Rod mill is in traditional closed circuit method crushing process, when most of material has reached fineness requirement, always there is the small part coarse powder to be mixed in wherein, make this part coarse powder further be crushed to the granularity that requires need prolong the pulverizing time significantly, make crush efficiency reduce, power consumption significantly increases; (2) it is poor that there are the material particular diameter uniformity after the classification in selecting crude drugs with winnower classification and grading wheel classification, influenced the quality of production of herbal medicine compound recipe superfine powder greatly, especially when being applied to the use of animal drinking-water, because a small amount of not existence of breaking cellular wall cell is difficult to reach instructions for use.(3) traditional one-way gas flow is sieved, because Chinese medicine is when carrying out micronizing, along with reducing of particle diameter, material particles surface area and surface energy increase, adsorptivity increases, and mobile variation easily is gathered into bulky grain etc. and causes the sieve classification of crossing that surpasses 200 order fineness medicated powder to be difficult to carry out.The existence of above-mentioned factor has had a strong impact on standardization, the large-scale production of herbal medicine superfine powder, and the popularization on veterinary clinic and use.
Summary of the invention
The object of the invention is to provide a kind of superfine powder huoxiang zhengqi powder normal temperature preparation method, efficiently solve that the energy consumption that exists in the present production is big, the medicine maximum particle diameter is difficult to accurate control, can't produce continuously, difficult problems such as dust is many in the production process, make the finished medicines of preparation have rapid-action, good effect, bioavailability height, effect that the clinical application amount is few.
Another purpose of the present invention is to provide a kind of special-purpose two-way airflow screening machine that is applied to superfine powder huoxiang zhengqi powder normal temperature preparation method.
Superfine powder huoxiang zhengqi powder normal temperature preparation method of the present invention comprises the steps:
The first step, choose crude drug Herba Pogostemonis, Folium Perillae, Poria, the Radix Angelicae Dahuricae, Pericarpium Arecae, Pericarpium Citri Reticulatae, Radix Platycodonis, the Rhizoma Atractylodis Macrocephalae (stir-fry), Cortex Magnoliae Officinalis, Rhizoma Pinelliae Preparatum, licorice piece respectively; Clean, dry or dry to moisture≤10%;
In second step, respectively that above-mentioned raw materials medicated powder is broken under 20 ℃~25 ℃ temperature, obtaining granularity is 60~120 purpose coarse powder;
The 3rd step, with the second step gained coarse powder in Herba Pogostemonis: the weight portion ratio mix homogeneously of Folium Perillae: Poria: the Radix Angelicae Dahuricae: Pericarpium Arecae: Pericarpium Citri Reticulatae: Radix Platycodonis: the Rhizoma Atractylodis Macrocephalae: Cortex Magnoliae Officinalis: Rhizoma Pinelliae Preparatum: Radix Glycyrrhizae=12:9:6:3:6:6:5:6:6:4:3;
The 4th step, with the 3rd step gained coarse powder place pulverize in the rod mill after, be fed into special-purpose two-way airflow screening machine by wind and cross 500 mesh sieves, the air-flow that the powder that obtains particle diameter≤25 micron of sieving is produced by air-introduced machine is transported to collect in the tornado feeder set and namely gets superfine powder huoxiang zhengqi powder finished product; The powder of not crossing 500 mesh sieves arrives circulation pulverizing again in the described rod mill through the funnel collection and by line transportation.
Special-purpose two-way airflow screening machine of the present invention comprises casing and the downward screen drum of chamber intermediate openings that sets within it, the order number of described screen drum 〉=500 orders; The nozzle of screen drum is connected mutually with the funnel upper shed that is arranged on the casing bottom; Chassis cavity is connected with air-introduced machine by the negative pressure chamber on top; Be provided with the door font rotary jet pipe that is constituted by transverse tube and standpipe in the zone between screen drum and casing, the puff prot of described door font rotary jet pipe is for axially being opened in groove on its tube wall along described transverse tube and standpipe respectively, described groove is offered towards the screen drum direction respectively, the groove width 0.5-2 millimeter of groove, the middle part of transverse tube and drive motors driving coupling; Be provided with blast pipe in the screen drum centre position, the air outlet of described blast pipe passes that screen drum is connected with the transverse tube middle part of door font rotary jet pipe and rolls by rolling bearing and is connected; The air inlet of blast pipe extends outside the described hopper side walls and is connected with the blast orifice of aerator; Be provided with feed pipe in screen drum, be provided with the buffering umbrella above the discharging opening of described feed pipe, the charging aperture of feed pipe extends outside the hopper side walls and is communicated with powder conveying fan air outlet through wind stopping device.
The air inducing of described air-introduced machine is pressed and is 1000pa, and the air inducing amount is 3000m 3/ h; The rotating speed of described drive motors is 155 rev/mins; The blast pressure of described aerator is 33kpa, and the blow rate required is 320m 3/ h; The wind pressure that goes out of described powder conveying fan is 24kpa, and air output is 150m 3/ h; The sidewall of described screen drum and roof respectively with corresponding standpipe and transverse tube between distance be 25 millimeters.
The invention has the advantages that whole process of preparation all carries out at normal temperatures, do not need low temperature or special additional conditions; Final drug particle diameter≤25 micron of preparation, cell wall breaking rate and bioavailability have been improved greatly, strengthened pharmacological action, thereby reduced treatment disease dosage, saved medical material, also improve simultaneously abnormal smells from the patient and the mouthfeel of medicine, make and directly adopt the water way administration to be achieved, changed the deficiency that Chinese powder medicine can only spice can not be drunk water and take; The two-way airflow screening machine that uses in the inventive method has been simplified the preparation technology of superfine powder huoxiang zhengqi powder greatly, has realized the purpose that the Chinese powder medicine quality standard is controlled, be suitable for large-scale industrial production.
The clinical therapeutic efficacy of preparation of the present invention is verified by following test:
